I ran into this website: and on it there is a link to be opened with the Ubuntu App center, but Firefox doesn't know what to do with it.
What I got to do to get it opened as it should?

You need to configure apturl in your browser:
In Firefox you need to change the setting also in Preferences->Applications Link the apt protocol to /usr/bin/apturl there.
You should check that the gconf setting /desktop/gnome/url-handlers/apt/command is software-center "%s" which is the default.
You can change that by using either using the graphical tool gconf-editor or from the command line to apturl:
gconftool --set --type=string /desktop/gnome/url-handlers/apt/command 'apturl "%s"'or for using the Software Center
gconftool --set --type=string /desktop/gnome/url-handlers/apt/command 'software-center "%s"'Source:
